Is there a way I can write the second context more concisely by referencing the first?
describe MyClass
let(:instance){MyClass.new}
describe '#myMethod' do
let(:input){ [1] }
context 'with input' do
it 'does stuff' do
instance.should_receive(:foo)
instance.should_receive(:bar)

Change values in a hash without modifying the origional?
arr = [{num: 1}, {num: 2}, {num: 3}]
arr.map{|h| h[:num] += 1; h} # [{:num=>2}, {:num=>3}, {:num=>4}]
arr # [{:num=>2}, {:num=>3}, {:num=>4}]
# is there a better way to do this?
arr = [{num: 1}, {num: 2}, {num: 3}]
arr.map{|h| clone = h.clone; clone[:num] += 1; clone} # [{:num=>2}, {:num=>3}, {:num=>4}]
arr # [{num: 1}, {num: 2}, {num: 3}]

How do you get this to not output 'foo' ?
class Foo
attr_reader :number
def initialize
puts 'foo'
@number = 1
end
end
describe Foo do

Is there a cleaner way to do this?
desc "Run cucumber tests on each feature file in parallel, exits 0 if they all succeed and 1 otherwise"
task :test, :exclude do |task, args|
features_to_exclude = args.has_key?(:exclude) ? args[:exclude].split(' ') : []
# actually task here
end
